Equivalent Air Depth (EAD) Calculator

The equivalent air depth(EAD) is the depth on air where we experience the same nitrogen partial pressure, absorb the same amount of nitrogen and incur the same decompression penalty for our actual depth on nitrox. Just enter values for “Oxygen Mix” and “Actual Depth” and hit “Compute MOD”

Oxygen Mix(O2%) – [1=100% or 0.21=21% etc]

Actual Depth – [0.0 – 1000.00] meters

Equivalent Air Depth(EAD) is: Metres.
